Escherichia coli K-12 substr. MG1655 Gene-Ontology-Terms Class: GO:0008236 - serine-type peptidase activity

Synonyms: serine protease activity

Definition: Catalysis of the hydrolysis of peptide bonds in a polypeptide chain by a catalytic mechanism that involves a catalytic triad consisting of a serine nucleophile that is activated by a proton relay involving an acidic residue (e.g. aspartate or glutamate) and a basic residue (usually histidine).
